Z27 doesn't wake up when switching computers

HP Recommended
Z27
macOS 10.15 Catalina

I'm connecting my Z27 using the included USB-C cable. I have two different MacBooks, both with Thunderbolt 3 ports. The connection works fine, but when I'm using the monitor with one computer and I unplug it and plug it into the other one, the monitor doesn't register any video input and turns itself off after a few seconds. The only way I've found to get the monitor to notice the video input is to unplug power from the monitor for a few seconds and then plug it back in. Obviously this is not the way the monitor should work. Has anyone encountered this and found other ways to get it working?

Figured it out: In my monitor settings, Input Control > AutoSwitch Input > Off. I'm guessing this turns off any logic that tries to detect what the monitor is connected to. I can now hot swap and the display comes up showing the new computer within a few seconds!
